ANDY Evans converts engines to liquid petroleum gas - and he is booked up for the next five weeks.

But with a litre of LPG costing as little as 31p, perhaps it is not surprising.

Mr Evans said his garage has been besieged with orders in the last few weeks.

And the Wirral-based mechanic is not expecting demand to drop. He said: "It's been going mad recently.

"I don't need to advertise at the moment - petrol prices are doing it all for me."

Mr Evans runs three family cars on LPG and has found no dip in performance, even for the Range he uses to tow his boat.

He said: "With the latest technology you wouldn't notice anything. I can run a 2.4-litre Toyota Previa with eight seats for the same price as a 1.2litre Corsa. I've had no complaints about performance and quite a few people have even said it's improved."

There is a drawback of course - converting to LPG costs £1,300.

* GO EASY on the air-conditioning if you want to cut your fuel bill.

An AA spokesman said: "If it's a hot day and you've got your air-conditioning running full pelt for a couple of hours you can almost watch your fuel consumption needle dropping."

The spokesman also advised motorists to stick to the speed limit on motorways as fuel consumption leaps between 70 and 80mph.

Other tips include making sure tyres are at the right pressure and that the car is as light and aerodynamic as possible.
